|
All of the fossils were found in the same layers of rocks as horse fossils.
|
|
|
All of the fossils are completely identical to horse bones.
|
|
|
All of the fossils show similar structures to that of the modern horse.
|
|
|
All of the fossils were located in the same place on Earth as horses.
|
Detailed explanation-1: -If all of the fossils show similar structures to that of the modern horse, it indicates that a series of fossils represent the evolution of the horse.
Detailed explanation-2: -Q. Which would indicate that a series of fossils represent the evolution of the horse? All of the fossils were found in the same layers of rocks as horse fossils.
Detailed explanation-3: -Evidence from Fossils The fossil record reveals how horses evolved. The lineage that led to modern horses (Equus) grew taller over time (from the 0.4 m Hyracotherium in early Eocene to the 1.6 m Equus). This lineage also developed longer molar teeth and the degeneration of the outer phalanges on the feet.
Detailed explanation-4: -Fossils help in establishing the time period in which organisms lived. Fossils provide good evidence of the structure and lifestyle of animals (and even plants) from the past. They provide a record of the remains of long-extinct species.
